Bending‐Shear Interaction Strength of Corrugated Web Beams Using HSS

Abstract In most of the cases these steel girders with corrugated web are used in bridges, however, they are also applicable for industrial structures. Stability issues are important, as flange buckling and shear buckling can occur depending on the geometrical layout. Corrugated web girders have greater shear capacity than conventional I‐girders proved by previous investigations. In addition, the flange buckling behavior differs from that of conventional I‐girders. While there have been only a few studies on the bending‐shear (M‐V) interaction behavior, however, there is a lack of research on the M‐V interaction of hybrid trapezoidal web girders having different steel material grades for the flanges and the web. Previous international studies give proposal for M‐V interaction for those of girders having homogeneous steel grade (same for the flanges and web). EN1993‐1‐5 Annex D [1] gives a proposal for shear strength and flange buckling resistance. Besides it gives reduction factor for bending moment when accompanying shear force acts. Therefore, this paper focuses on the M‐V interaction behavior of hybrid steel trapezoidally corrugated web girders (different flanges and web steel grades).
